OPERATION
Sap from palm trees may corrode metal parts unless proper saw
maintenance is performed. Make sure to clean metal parts from palm
sap immediately after use.
• Remove sprocket guard. Clean wood chips and sawdust from guard and
engine crankcase.
• Never use metal tools for cleaning which can scratch the metal paint and
allow corrosion to develop.
• Clean sap accumulation from metal parts with cloth and warm water with
soap.
• Rinse with clean water and dry metal surfaces.
• Apply a light coating of engine or bar and chain oil to metal parts after
they are cleaned.
• Install and properly tension guide bar and chain. Run engine for one
minute alternating engine speed between full throttle for five seconds and
idle for five seconds to coat metal parts with additional protective chain
oil.
Do not run a chainsaw not under cutting load at wide open
throttle longer than five seconds or engine damage can
occur.
Keep chain properly tensioned during operation to prevent
the chain from jumping out of the guide bar rail slot and
damaging metal engine parts.
